KEY-FASTENER.

SPECIFICATION forming part of Letters Patent No. 366,150, dated July 5,1887.

Application filed May 1 1, 1887. Serial No. 237,907. (No model.)

To all whom it may concern:

Be it known that I, JAMES BUSFIELD, a citizen of the UnitedStates,residing at Haw erhill, in the county of Essex and State ofMassachusetts, have invented a new and useful Improvement inKey-Fasteners, of which the following is a specification.

The object of my invention is to produce a key'fastener that can readilybe secured to a [0 door by a single screw, and which, when applied tothe key, will securely hold the same, so that it will be impossible toturn the key from theoutside, and when not in use will li flat againstthe door out of the way.

The invention consists of a furcated wire having its outer ends bentover and secured at its inner end to the door by a slotted plate, thewire forming a spring, so that it can be compressed to pass through thebow of the key. Referring to the accompanying drawings, Figure 1represents a perspective view of a portion of a door stile with lock,and a keyfastener embodying my invention as applied to the key. Fig. 2is a similar View showing I the position of the fastener when not inuse.

Fig. 3 is a horizontal section taken 011 line no at of Fig. 2. I

A represents the door-stile, B the lock, 0 the knob, and D the key.

E is a metal plate provided with a slot or groove, 0, and secured to thedoor-stile A by a screw, F. V

G is a furcated wire secured to the door by the plate E, the wire Gbeing free to move up 5 and down in the slot or groove 0. The furcatedwire G is bent to the form shown-that is, contracted at g to form aspring and bent over at its outer ends, h h.

To apply the key-fastcner the plate E is first secured to the door-stileA in the proper position by the screw F. The two ends of the furcatedwire are then taken between. the finger and thumb and compressed Thewire is then pushed up so thatits outer ends, h 71', will pass throughthe bow D of the key D, when the key will be firmly secured, as shown inFig. l, the bent-over ends h preventing it from slipping out of the bowD". \Vhen it is desired to release the key, the ends of the wire areagain compressed and the wire pushed down,whenthe outerends, h,will passthrough the bow D and the wire G will fall into the position shown inFig. 2.

To hold the wire down against the door stile A, I form a groove, f, oneach side at the lower end of the plate E, (see Fig. 3,) so that whenthe wire G is placed down it will snap over the edges of the plate E andbe held in the grooves f, as shown in Fig. 2, so that it will not swingout when the door is opened or shut.

It will be seen that by means of the slot or groove 6 the wire G can beraised or lowered, according as it is required to attach it to or detachit from the key.

What I claim as my invention is- The plate E, provided with a slot orgroove, 0, and grooves ff, in combination with the furcated spring-wireG, contracted at g, and having its outer ends, h, bent over,substantially as and for the purposes set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

' JAMES BUSFIELD.
